Girlie, it sounds like what you have may be the industrial grade. Be sure and check before using it! You should only use food grade according to the link that astroman shared. :)
Both the industrial and food grade kill insects. It's not the contaminants in it that kills them, it's the way the DE works.
The insects 'dry' up. It works mechanically, not chemically.
It is not healthy for anyone to breathe it in...bad for the lungs. (even food grade)
I don't think ours is the 'pool' grade...we bought it at the nursery when getting our plants....so it's most likely not food grade either. Maybe there are three grades.
I am not using it for detox - just killing the dang carpenter ants...
